Profile Summary

This Head of Security builds robust, scalable enterprise security programs that protect critical assets and enable business growth. They are a strategic builder, designing and implementing security architectures that integrate seamlessly into complex environments, fostering a culture of security by design across large organisations.

Problems Solved

  • Architected and deployed a cloud security posture management (CSPM) solution across a multi-cloud environment (AWS, Azure) for a major Australian financial institution, reducing critical misconfigurations by 75% within 12 months.
  • Led the overhaul of an incident response framework and playbook, decreasing average incident containment time by 40% and post-incident review cycles by 30% for a leading tech unicorn.
  • Developed and implemented a data loss prevention (DLP) strategy for sensitive customer data, resulting in a 90% reduction in exfiltration attempts and achieving compliance with APRA CPS 234 for a large enterprise.

What They Build

They build comprehensive enterprise security programs, including security architecture, risk management frameworks, and incident response capabilities. Their focus is on creating secure-by-design systems and processes that empower engineering teams while maintaining a strong security posture.

What Would Make Them Move

Looking for a CISO or VP Security role where I can build the function from scratch. Need board-level visibility, direct CEO reporting line, and a company that treats security as a business enabler, not a cost center. Equity is important — I want skin in the game.

Mission & Values

I have seen too many enterprise security programs that exist on paper but crumble under pressure. I want to build programs that actually work when it matters — not just pass audits.
